Subject: [PATCH] guix-install.sh: Fix chk_require exiting without warning.

* etc/guix-install.sh (chk_require): Because of the set -e option, Bash was
exiting when the command `command -v "$c" &>/dev/null' was running on its
own. Instead, we now test the command and accumulate warning messages in a
single statement by chaining the command with a logical OR.
